Identifying Deception through Nonverbal Communication
General Purpose: To inform
Specific Purpose: To describe to my audience an overview of research-proven changes in nonverbal communication that indicate a person is being dishonest.

Often when a person is being untruthful or does not agree with what they are saying, their nonverbal cues indicate as much. Identifying these inconsistencies can help indicate whether or not a person is being upfront. IV.

Chapter 4 on nonverbal communication spurred my interest in this topic. V. Preview Points: There is no set nonverbal cue or universal behavior that everyone uses when they are being dishonest. There are, however a number of things to which a person can pay attention to determine another’s truthfulness.
